I'd prefer not to. Most uses of #ifdef CONFIG_PM that get introduced are wrong,
and cause additional randconfig warnings that I end up having to fix,
so I always
do it with __maybe_unused.
I don't mind if you treat my patch as a bug report and decide to fix
it differently
yourself, but you won't get that patch from me ;-)
